Filed Oct. 31, 1962, Ser. No. 234,440 6 Claims. (Cl. 189-75) Thisinvention relates to a metal window and easing combination, particularlyconstructed of metal.

An object of the invention resides in the provision of a window frameassembly which includes a sash frame and positioning and retaininganchor members which may be twisted on to the jambs, sill and header andwhich may be attached in window openings defined by various wallconstructions and in walls of dilferent thicknesses.

A further object of the invention resides in so constructing the anchormembers that they will serve to rigidify the sash frame to the metalcasings of various depths when such are employed, and to maintain thecasings in a given relation to the sash frame and in the Window opening,without the additional anchorage usually employed.

Other objects of the invention will appear as the description of theillustrated embodiment of the invention progresses.

In the drawing which illustrates this embodiment,

FIGURE 1 is a vertical sectional View disclosing a position of the silland header anchors in relation to the window sash frame and easing;

FIGURE 2 is a horizontal sectional view showing the relative position ofa jamb anchor; and

FIGURES 3, 4 and 5 are perspective views of the header, sill and jambanchors.

Referring to the drawings, the sash frame is indicated generally by thereference character A, the casing by the reference character B and theanchor members on the sill, header and jambs by the characters C, D andE, respectively.

In the metal frame window industry, the sash frame A and the casing Bare attached together in a number of different ways, but in thedrawings, we have shown a recess or horizontal channel 2 in the sill 3of frame A formed by rearwardly extending spaced parallel flanges 4 and6 at the inner edge of said sill. The recess or channel 2 receives andsecures between said flanges the depending flange 8 at the front edge ofthe horizontal lower plate or wall portion 10 of the casing B whichflange is forced or snapped into the channel 2.

The header 16 of the sash frame and the upper horizontal wall portion 10of the casing are secured together in a similar manner to that employedin securing lower wall 10 to the sill.

The jambs are each provided with similar but vertical channels 12defined in part by rearwardly extending inclined flanges 61, FIG. 2 andeach receives a similar flange 14' on the vertical wall portions 14 ofthe casing, FIG. 2.

According to our invention one or more anchors are used in connectionwith each of the sills, headers and jambs to secure and position thesash frame and casing in respect to the window opening. In the drawings,we have shown, for the purpose of illustrating our invention, one anchorfor each of said frame elements.

The anchor C for the sill is attached to the sill and to the framing ofthe window opening regardless of the character of the material of thatframing.

To effectuate this attachment the sill 3 is, adjacent its outer edge andat its under side, provided with a longitudinally extending channel-20which, so. far as the anchoring at the sill is concerned may extend thefull length of the sill or partially thereof. This channel is formed inpart by an inwardly directed flange 22 in cooperation with the sill. Theopposite or inner edge of said sill 3 is provided with a similar channel24 which is formed in part by a flange 26 in cooperatioin with the sill.Additionally, when a casing is used, its lower wall portion 10 is formedwith an angle flange 60 to provide a channel 28 at the rear edgethereof, said flanges 8 and 60 in eflect defining with wall 10 an openside channel of which ,rear channel 28 is a part.

These channels in sill 3 and wall 10 are for the purpose of receivingvarious parts of the sill anchor C which comprises, FIG. 4, a toeportion 30, a heel portion 32, an intermediate portion 34 and a shankportion 36, a supporting base 38 and an attaching plate 40 forattachment of the anchor to the building structure.

The heel portion 32 is provided with a resilient laterally extendingprojection 33 which extends therefrom at an angle somewhat greater thana right angle so that when the anchor is twisted and snapped into placein the position indicated in FIG. 1 and with projection 33 bearingyieldingly against the inner surface of the base of channel 28, theprojection 33 will assist in maintaining the anchor in effectiveoperative position wherein the end of the toe portion 30 is seated inchannel 20, the intermediate portion 34 in channel 24 and the heelportion 32 in channel 28.

The shank portion 36 supports the inner edge of sill 3 and the lowerplate 10 of the casing so that no additional reinforcing of said silland said casing is required to prevent deflection or deformation of theassembly of said parts when the sill or the casing is subjected toweight.

When manually positioning the anchor C in engagement with the sill asdescribed, the anchor is initially canted off at an angle to its finalposition and, as shown in FIG. 1, the toe portion 30 is placed in thechannel 20. As the anchor is swung from said initial angular position tonormal substantially perpendicular position, the intermediate portion 34will snap into the channel 24 due to the slight resiliency of the metalof the anchor and, as the swinging movement is continued, the heelportion 32 and laterally projecting flange 33 will snap into the channel28 in the casing due to the resiliency and position of the projection33.

The flanges defining these channels, as 20, 24 and 28, and theresiliency of the metal of the anchor will hold the anchor in positionso that when it is attached to the building structure as by a bolt, orthe like, not shown, passing through a hole 5 in attaching plate 40, thesill and the casing will be anchored and positioned at once.

Although the header anchor D is of somewhat different form than the sillanchor it has portions which act in substantially the same manner toanchor and position the frame and easing at the header.

Thus, the header 16 of the frame has an outer channel 20 formed by aflange 22' in cooperation with the header, and an inner channel 24'formed in part by a flange 26 in cooperation with the header and anouter channel 9 formed in part by a bent down flange 11. The top wallportion 10' of the casing B has a channel 28 defined in part by angleflange 60 at its rear edge and an upturned flange 8' at its front edgewhich is operatively retained in channel 9 by flange 11 of the frame.

The header anchor D is provided with a toe portion 30', FIG. 3, anintermediate portion 34' and a rear portion 32' which portions snap intothe channels 24' and 28', respectively.

The heel portion of anchor D includes a resilient projection 33' whichextends therefrom at an angle somewhat greater than a right angle sothat when the anchor D is snapped into place, FIG. 1, the resiliency ofthe projection will assist in maintaining it in its proper position.

The toe portion of the header anchor D is also provided with apositioning slot 42 which engages the adjacent flange 22' of the frame;and the anchor D advantageously includes a fastening plate 38' havingholes 48 adapted to receive bolts or the like for attachment to thebuilding structure.

In assembling, the header anchor D is canted and moved manually intoposition in a manner similar to that employed in connection with theapplication of the sill anchor C, the slight resiliency of the metalcooperating to facilitate operation when the fit is tight.

The jamb anchor E is functionally similar to the sill and headeranchors, differing, however, in some structural details. Thus, FIG. 5,it has the toe portion 50, the heel portion 52, the intermediate portion54 and the shank portion 56 all conveniently embodied in the form of aflat plate. Toe portion 50 thereof has a slot 51 and intermediateportion 54 has a slot 55. To operatively position anchor E the toe andintermediate portions 5% and 54, respectively, are initially canted and,as seen in FIG. 2, snap into channels in the jambs of the sash frame,similar to those in the header and sill, while the heel portion52 snapsinto the channel 28" defined in part by rear angle flange oil" in thecasing. Also slot 51 engages flange 57 and slot 55 engages flange 59.

The shank portion 56 of this jamb anchor E has bolt holes 58 adapted toreceive bolts by which the plate may be attached to the buildingstructure either in a previously formed window opening or as the masonryis built up.

in the case of anchor C, the distance preferably between the open sidesof the toe channel 263* and of the intermediate channel 24 is less thanthe distance between the extremities of the toe portion 30 and theintermediate portion 34 of said anchor C; and the intervening portion ofthe anchor is somewhat resilient so that, when the toe and intermediateportions of the anchor are snapped into the channels 26 and 24 from acanted position, the anchor will be maintained in its predeterminedrelation to the frame.

For a like purpose the distance between the open side of the toe channel20 and that of the heel channel 28 in the casing is less than thedistance between the extremities of the toe and'heel portions of theanchor so that the heel portion resiliently will be held in position.

For more effective interlocking of the parts and as seen in FIGS. 1 and4, an edge of anchor C is notched at 35 to engage flange 26, FIG. 1; anedge of anchor D is notched at 37 to engage flange 26; and anchor E isnotched at 51 to engage flange 57 as above noted. These notchesoperatively engaging the corresponding flanges serve along with theresilient characteristic of the anchors to effectively stabilize saidanchors in their several operative positions in the assembly.

From the foregoing description it appears that we have provided anchorsfor the sash frame and easing which may be manually snapped intoeffective locking or engaging relationship with the sill, header andjambs and be attached to the building structure to anchor and maintainthe sash frame and casing in position in a window opening regardless ofthe material employed in the building structure.

Thus by manually canting the anchors and applying pressure thereto inassembling, the casing, sash frame and anchors may be installed inminimum time and with minimum effort without the use of tools. When soassembled, the sash frame and casing and anchors will maintain thedesired relationships and rigidity when installed in a window opening.
